Convexity of oligopoly games without transferable technologies

摘要: We present sufficient conditions involving the inverse demand function and cost functions to establish convexity of oligopoly TU-games without transferable technologies. For convex it is well known that core relatively large generically nonempty. The former property provides us with an answer about stability cartels, latter gives indication incentive found a cartel. Furthermore, for games kernel singleton in Shapley value located center gravity core, thus, there are natural solutions available split benefits cartel agreement.
